Ok, I finally came around to some more debugging. My problem has to do with
windows/message.c/process_raw_mouse_message. Here it is determined
if a new buttondown should be converted into a doubleclick. The test right
before that
if (GetClassLongA(msg->hwnd, GCL_STYLE )&CS_DBLCLKS || ht!=HTCLIENT)
fails always and therefore I never get a doubleclick on my dialog.
msg->hwnd is NULL, GetClassLongA returns 0x4800, ht is 1 (=HTCLIENT), so
both conditions fail but I don't know where the error(s) is(are) now.
Why isn't it "allowed" to doubleclick on the empty background (HTCLIENT)?
Thanks for any hints.
